SPECIFICATION forming part of Letters Patent No. 78d,108, dated March'7, 1905.

Application filed February 12, 1904:. Serial No. 193,345.

To all whom, it TIMI/,7] concern.

Be it known that we, l/VILLIS H. FISHER, a resident of Memphis, in thecounty of Shelby and State of Tennessee, and IIENRY B. Hnmi and ,G-noneuErPLn, residents of Shreveport, in the parish Cad do and State ofLouisiana, citizens of the United States, have invented new and usefulImprovements in Hydraulic Hand-Cars for Railroads, of which thefollowing is a specification.

Our invention relates to a hydraulic construction or reconstructionhand-car to be used on railroads, and the main object that we have inView in producing such a hand-car is to reconstructand even up railroadswhere such have become irregular and unlevel from the weight of the carswhich travel over said roads.

Our invention is so constructed that sunken or settled portions of theroad can be readily grappled and raised without the use of handspikes orcrowbars.

Figure 1 is a side elevation disclosing one side of the hand-car inposition on a rail, also the position of one of the hydraulic rams, ofwhich two are employed for raising the track on each side of the road atthe same time. Fig. 2 is a cross-section of the car, showing the tworams in vertical section. Fig. 3 is a plan view of our construction,showing the location of two hydraulic rams located centrally between thefour wheels oi? the car, also the location of a force-pump employed forforcing water into the two rains at the same time.

With the above description we will now proceed to more fully describeour invention by referring to the corresponding characters on thedrawings and the specification and will first describe the route of thewater from a watertank 1 to the rams and its return back. to said tank.The numerals, commencing with 8, will correspondingly indicate the routeof the water from T-joint 7 to its entrance in each of the largeram-cylinders, and corresponding numerals will indicate the route of thewater from this point to the small rams,

l and also corresponding numerals will indicate the return of the waterfrom the rams back to the tank.

A-force-pump 2 is placed on the top of the platform of the car-3innncdiately over the tank, with a suction-pipe 4 connected to the lowerend of said pump and extending downward within a short distance from thebottom of the tank. lhe pump is next started by an upwardand-downwardmovement of the handle 5. The water is then drawnu p through the pipeand is forced out through pipe 6, which connects to a T-joint 7. FromIF-joint 7 it is forced each way through pipes 8, said pipes connectingelbows S). Extending from said elbows i) are pipes 10, which connectelbows 11. Extending from said elbows 11 are sections of pipe 12. Saidpipes 12 connect to elbows 13. Said elbows 13 connect to vertical pipes1 1. ((llearlyindicated at Fig. l.) Said pipes connect to IF-joints 15.From said 1- joints, connecting with the upper ends of the hydraulicrams proper, are short sections of pipe 16 Secured to said sections 16amoneway valves A. Extending vertically from said T-joints 15 are sectionsof pipe 17. Connected to said sections are elbows 18. Extending fromsaid elbows in and connecting to ram extensions 19 are horizontalsections of pipe 20. Connected to said horizontal sections 20 areone-way valves B.

We will now describe the route of the water from the respective rainsback to the watertank 1. Extei'iding from ram extensions 19 are shortsections of pipe 21. To said sections of pipe 21 are one-way valves.Said sections connect to elbows 22. .ltlxtending from said elbows areshort sections of pipe 23, con.- necting to T-joints 24. This brings thewater back from ram extensions 1%) to vertical pipes 14, clearlydescribed. Leading from the hy draulic rains proper to "l"-joints 2 1are short sections of pipe 25. (Jonnected to said short sections areone-way valves 1.). Extending from said T-joints 24: and coi'n'iectingwith elbows 26 are vertical pipes 14-. From said elbows 2.6, connectingwith elbows 27, are short sections of pipe 28. From said elbows 27 andextending back to and connecting with watertank 1 are sections of pipe29.

e will now proceed to describe the construction of the rams 30 and 30.Corresponding numerals will indicate the corresponding respective partsof each. These are each provided with piston heads 31. Said pistonheadsare hollow the greater part of the length thereof and are provided withextending legs 32, adapted to extend down to the ground. Each of saidlegs is forked, as plainly indicated at Fig. 1. Attached to their lowerends are feet or shoes 33. Said pistons a sufiicient distance above saidforks are provided with crossbeams 34. Connected to said crossbeams aredepending cars 35. Pivotally secured to'said depending ears aredepending grapplinghooks 36. These hooks extend downward and are adaptedto engage the under side of a railway-rail, as shown. Secured to saidextending legs 32 at the forks thereof referred to are chains 37, thelower ends of which are secured to the lower ends of the depending hooks36. Said piston-heads 31 are further provided with circumferentialpistonrings 38. Secured to the upper end of said piston-heads 31 arevertical piston-rods 39. Said rods extend upward through the tops of therains proper and through the bottom of the ram extensions and areconnected to pistonheads 10 in said ram extensions 19.

The operation of our invention is as follows: The machine is placed uponthe railway-tracks. Tank 1 is filled with water. Pump 2 is put in motionby an upward-anddownward movement of the handle 5. The water is drawn upfrom tank 1 to pipe 1 and forced out through pipe 6, where it extendseach way through pipes 8, from pipes 8 to elbows 9, through pipes 10,through elbows 11, through pipes 12, through elbows 13 and up throughpipes 1 1 to T-joints 15, from T-joints 15 through short pipes 16 tohydraulic rams 30, but continues to ram extensions 19, through verticalpipes 17, through elbows 18, and through pipes 20 to ram extensions 19,when the machinery is in the position indicated at Fig. 2. For raisingand leveling the sunken portion of the track, but before the waterenters the water-chambers 41, the one-. way valves B and D are closed.This will prevent the water from entering ram extensions 19anddischarging from rams 30. WV hen this is done, the water is to passin through valve A to the water-chambers 41. This will bring to bear apressure between the upper ends of the piston-heads 31 and the top ofthe rams 30, and by the feet 33 on the extended legs 32 being on theground the car with the hoisting apparatus will 'move upward, carryingthe tracks with it, as indicated,in the direction by dotted lines, fromthe fact that the grapplehooks firmly grapple the under side of thechains 37.

rails, which are usually spiked down tight to the ties. hen the sunkenportion of the tracks is in this position, the earth and ballast isstamped in under the ties, when the machine is ready to move on to thenext low point.

We will now describe the purpose of the ram extensions 19 in connectionwith the Before the car is moved to another defective part of the trackit will be necessary for the grap1')lehooks to be raised to a positionsufficient for the lower ends of said hooks to pass over the top of theties. In order to accomplish this, the one-way valves A are closed andthe two-way valves are open. Then with a few wrenches on lever 5 of theforce-pump 2 the water is forced into ram extensions 19 between thelower ends thereof and piston-heads 10. Said piston-heads 4E0 are forcedupward, which raises piston-heads 31 of the rams proper. In thisoperation the chains 37 cause the grappling-hooks 36 to spread outwardbetween the forks of the extending legs sufficiently far to let saidgrappling-hooks pass over the tops of the ties.

In order to let the water discharge from the water-chambers 31, theone-way valves D are open, and in order to let the same discharge fromthe lower ends thereof ram extensions 19 and the one-way valves C areopen.

Having now fully described our invention, what we claim as new, anddesire to secure by Letters Patent of the United States, is
